Learn SIMULA with Real Code Examples

Obtain a Simula compiler (historical or open-source implementation)

Install compiler and configure environment variables

Verify installation with a sample program

Check standard library support

Ensure simulator constructs are available for testing

Install historical or open-source Simula compiler

Set PATH to compiler and runtime libraries

Verify installation with sample simulation

Check standard classes and coroutines availability

Prepare test scenarios for learning and debugging

source.sim - main source file

lib/ - reusable class modules

bin/ - compiled executables

tests/ - simulation scenarios

docs/ - documentation and notes

simc source.sim - compile Simula code

simrun executable - run simulation

simbuild project - link multiple modules

simtest tests/ - run test scenarios

simversion - check compiler version

Supports standard character sets

External visualization tools handle localization

Simulation outputs can be formatted per locale

No native i18n library

Educational adaptation possible

Keyboard and console-based interaction

Text outputs for educational accessibility

Modules can abstract simulation parameters

Lightweight computational footprint

Primarily academic accessibility support

Simula has no native GUI

Text-based simulation outputs

Visualization handled externally

Educational tools may provide graphics

Simulation results can be plotted or exported

Objects encapsulate state

Instance variables per object

Coroutines manage process states

Simulation variables tracked in event queues

State transitions via method calls and process scheduling

Primitive types: INTEGER, REAL, BOOLEAN

Objects with instance variables

Queues and process structures for simulation

Structured records for modeling entities

Type safety ensures valid data handling
